Use the menu on the left or the search to find the information you need. Some starting points:


Since March 2021 Gateways are available that are based on the ESP32. Not all documentation is updated yet for these new products. In particular take care when you update the firmware. Do only use ESP8266 firmware for all Gateways except for the Gateway S32 and E32.

Sometimes the menu on the left doesn’t scroll properly. Via the Table of Contents below you can see it all.
